APPARATUS FOR HEATING STREET-CARS AND OTHER VEHICLES.

SPECIFICATION forming part of Letters Patent No. 311,151, dated January20, 1885.

Application filed January 18, 1.884. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN E. THOROUGH- eooD, of Des Moines, in the countyof Polk and State of Iowa, have invented a Car-Heater, of which thefollowing is a specification.

My invention consists in the construction and combination of a furnace,a furnace-box and hot-air chamber, a hot-air register, an outside casingand cold-air chamber, a furnace-blower, and a steam-generator andheatradiator with the floor of a car or vehicles of various kinds andforms, as hereinafter fully set forth.

Figure l of my accompanying drawings is a top view of my heater fixed toa section of a car-Hoor. Fig. 2 is atop view showing the car-floor andupper portions of the furnace box and case removed. Fig. 3 is atransverse section of the complete heater. Fig. 4 is a sectional viewshowing the blower detached and the steam-generating tube exposed. Fig.5 is a top view of the blower and a drawer combined.

J ointly considered, these figures clearly illustrate theconstruction,application, and operation of my complete invention.

A represents the fioor of a car.

B is a square metal frame provided with a flange on its outside topedge, to adapt it to be tted in and fixed to the edges of acorresponding opening in the door of a car.

C are the metal sides of a square box, riveted or bolted to the underedge of the frame B.'

C is the bottom of the box,xed to the lower edges of the sides C, toform a support for a furnace, and to produce a hot-air chamber, No. 1,on the outside of the furnace or hrepot.

C are sides of the furnace. They have flanges at their edges, adaptingthem to be secured to each other and to the top d and base C by means ofrivets or screw-bolts. The insides of the plates or side pieces, C",have a corrugated surface or ribs extending vertically, to prevent fuelfrom packing too close against them.

D is a cover hinged to the furnace-top D in such a manner that it can beclosed air-tight and locked by means of a wedge-key, or in any suitableway, to prevent the escape of gas 5o at all times, and fire if a carshould be derailed and inverted.

D is a grate pivoted in the bottom of the fire-pot andcombustion-chamber of the furnace.

F represents a smoke-line extending laterally from the top portion ofone of the sides C, and through the parallel side C of the box, to becontinued to the side, end, or top of the car, as may be desired. v y,

F represents an opening on the opposite side ofthe furnace, throughwhich fuel may be introduced from a reservoir located under the seat inthe car, orin any position desired, so that the cover D need not beopened Ito supply fuel to the fire.

F (shown in Fig. l) represents a hot-air register detaehably placed uponthe frame B and over the hot-air chamber No. 1, that surrounds thefurnace.

F is a perforated plate detachably placed upon the frame B and over theregister F.

G G represent a sheet-metal case surrounding the box which incloses thefurnace. It has a iiange at its top edge, adapting it to be fixed to theunder side of the car-floor by means of screws. It inclines toward thebottom of the combined box and furnace, and is tightly fixed thereto bymeans of a flange extending inward, or in any suitable way, so as toproduce a cold-air chamber, No. 2, around the box and furnace.

h (shown in Fig. l) is an opening that admits cold air from above thefloor of the car into the chamber No. 2.

I are flanged tubes fixed in openings formed in the lower portions ofthe sides G of the box, to allow cold air to enter the lower portion ofthe hot-air chamber No. l, and to exclude dust. the iioor of the carbecomes heated by radiation from the furnace Wall or 'plates C", andascends through the hot-air register F into the car to the roof of thecar. A continuous The cold air thus taken from the top of 9o current ofheated and purified air is thus pro- 9 5 i blowershave extended inwardfrom the opposite sides of the furnace to the center, and

box that incl oses the furnace. It has a depressed center, that forms achamber, No. 3, adapted to receive a drawer immediately under thefurnace-grate D, through which ashes and cinders may fall.

M is a slide fitted to the side of the box in such a manner that it canbe moved down over an opening, N, in the box and into a drawerunderneath, to regulate the quantity of cold air admitted under thefurnace-grate and the supply of oxygen into the furnace, as required, togovern the combustion of fuel and the generation of heat. This slide Mmay be retained elevated at any point desired by means of setscrews N,that extend into the box-plate G through slots N, or in anyothersuitable way.

It represents a drawer adapted to fit and slide in the chamber No. 3.

It is a cover fixed over the front portion of the drawer that remainsoutside of the chamber No. 3.

R is a slot in the cover It', through which slot the slide M descends toprevent cold air from entering the chamber No. 3 whenever the re is tobe checked in the furnace and the heat in the car diminished.

S S are flaring and open-ended blowers that extend laterally from theopposite sides and front covered end ofthe drawer R. They are preferablyformed integral with the sheetmetal drawer, but may be attached theretoin any suitable way. As a car is moved air is caught and pressed throughthese blowers to be conducted to the fuel, to promote and regulatecombustion and heat in the furnace.

X represents a metal tube coiled around the furnace and within thehot-air chamber No. l. One of its ends passes outward at the bottom andthe other at the top, to be extended within adouble car-floor or on topof the floor and under seats, and joined at their extremities, asrequired, to produce a continuous tube and the circulation of steam andwater. I preferably fill the tube partly with salt brine, that will notfreeze readily. Vhen it is brought to a boiling` heat in the lowerportion of the coil in the hot-air chamber, steam will be generated andpressed to the remote end and highest elevation of the continuous tube,and the tube will serve as a radiator to aid in heating the car. As thesteam eondenses it will return to the lower portion ofthe tube and coilto be again heated, and thus continuously circulated and utilized..

From the foregoing detailed description of the construction and functionof each element and sub-combination the unitary offices of all the partsand the practical operation of my complete invention will be obviousA tomechanics and persons familiar with the laws of heat.

I am aware that furnaces have been fixed under the floors of cars, thatfunnel-shaped provided with separate dampers for regulating the draft,and that a coiled tube has been l combined with a stove andradiating-tubes in a car to generate and circulate steam to warm the airin a car; but my manner of constructing and combining metal plates toproduce a complete furnace, of forming and combining a chamber andblower with the furnace, and my manner of arranging and combining acontinuous tube with the furnace and car to generate and circulate andradiate heat, are novel and greatly advantageous in accomplishing theresults contemplated.

I am also aware that water-heating tubes have been combined withlhot-air furnaces, and that a furnace has been inclosed in a water-jacketpendent from the car-floor, to heat water and circulate it through atube that extended into the car; but my manner of combining awater-heating and radiating tube with a furnace inclosed in a box thatis pendent from a car and incased and enveloped by a cold-air chamber,so that the heat radiated from the furnace-walls and from the pendentbox enveloped by the cold-air chamber and that portion of the tubecoiled around the furnace and within the box will all be utilized byascending into the car to aid the watercirculating and heat-radiatingtube in maintaining an even warm temperature within the car, is noveland greatly advantageous, in that fresh air is thereby constantly passedthrough and heated in the apparatus and circulated in the car.

I claim as my inventionl. The combination of the square metal frame B,the four metal sides C, having flanges at their edges, the bottom orfurnace-support C, the furnace-sides C, having continuous iiangesextending outward from their edges, and vertical corrugation's on theirinside faces, the fixed top d, the hinged cover d, and the plate K,adapted to form achamber under the grate, substantially as and for thepurposes specified.

2. A sliding drawer having blowers S S and a chamber at its front end,in combination with a furnace suspended from a car-floor, and providedwith a chamber under the furnacegrate adapted to receive the slidingdrawer, for the purposes set forth. l

3. The drawer It It', having a slot, It", and the slide M, incombination with the boxG C and furnace-bottom K, to operate in themanner set forth, for the purposes specified.
